To all whom 'it may concern:

Be it known that i, Jesiden W, WtNKnLniso, o subject; oi the King of Great Britain, residing at i elson, British Columbia, in the Dominion of tanada, have invented new and useful Improvements in Wrenches, of which the following is :t specification.

My invention relates to wrenches, and its primary object is to provide o novel and highly useful device of this eharaeter wherein the movable jaw has a wide range oi adjustment, one ol' which is provided 'with means by which the movable jan' may be loeied securely in adjusted pt ,ion and released readily and quickly, one whieh i simple and durable, and one which may be imnniiaetured and sold a. (,-oinparatively low eost.

With the above and other objects in view, the invention consists oi the construction, combination and arrangement oi parts hereinafter' i'ully described, claimed and illustrated in the accompanying drawings, whereinz- Figure l is a side elevation ol' a wrench cmistrueted in accordance with my invention. .Fiel 2 is a similar view, portions oi the wrench he" g in vertical longitudinal section. liig. 3 is :i transverse section on the line 3-ll ot` Fig. looliinl in the direetion indicated by the `arrow, and Fig. Ll is a similar view on the line 4 4 et F' itc-terrinel to the drawings by reference numerals, 2 designates a shank whit-h is provided at one end with a lixed jaw 2*, and whit-h has itsother end reduced to provide a, stem Ai. The under et of the stem Ll is provided with teeth o and n longitudinally extending recess t'g, while the upper edge thereoll is rounded. A movable jaw 7 is mounted upon the shank 2 and provided with a stem t. This stem is parallel to the stem Al and a portion ot its upper edge is provided with teeth t), which are adapted to be brought into engagement with the teeth 5 to lool; the movable jav.'Y in adjusted ol' the spring 'to the bottoni wall oi said recess, and il, is bowed at a point internnaliale its ends: and has it: t`rerend disposed and movable in the ret-ess ti,

tin'ongg'honl bly mounted upon the renter por stems L -8 and is adapted to be manipulated to either move the stein 8 in the direction oi the stem 4 to cause the teeth of the stems to interlock and thus secure the movable jaw 7 in adjusted position, or to permit'. the Stern 8 to be moved away from tlxestem 4 by the action of the spring 10 to withdrew the teeth i rom engagement with each other and permit the movable jaw to be adjusted. When the handle is revolved upon the stems to position its greater diameter transversely of the wrench7 the stem S is iree to be moved from the stein 4 by the action oi' the spring 10, thereby withdrawing the teeth 9 troni engagement with the teeth' and permitting the movable jaw to be adjusted.V When, however, the handle is revolved to position its lesser diameter transversely oi the wrench, the stem 8 is moved in the direction of the stem 4, thereby bringing the teeth J in engagement with the teeth 5 and looking the'movable jaw 7 in adjusted position.

ln order to permit the handle to be revolved in a. plane concentric,` with its longitudinal axis, the outer end thereoi is circularin cross section and mounted upon a disk l-l carried upon a threaded bolt l5 projecting trom the end of the stem 4, said disk being secured in applied posit-ion by a nut lo. outer ond oi the handle 13 in :L manner to prevent the handle iront becoming accidentally displaced;

From the foregoingr description, taken in connection with the accompanying drawings, the construction and mode ol operation of the invention should be understood without a further extended description.

Changes in the form7 proportions and minor details el' Construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having fullj described and illustrated my invention, what l claim is:-

A wrench eonmi'slne a shank having; a Iixed jaw at one rnd and :t redueed portion l'orminen stem und :i shoulder, tet-th on one side of the stem, a mova'ole jaw havin.Y a stent. teeth on ille seeond stem adapted to engage those of the lrs, a spring arranged between the stems tto hold the teeth normally out ot engagement. a retaiui means on the outer end ol` the stem ot' the shank and serving :is u hearing'. u ringe, ysecured against the shoulder or" the shtml: which eut'u whieh the Avond stein slulnhly mores, and a sleeve 0 l` elliptical er1 Vseeiion surrounding hoth stems for engaging or (linen "in: the teeth ot' the latter :intl located with its ends engaging.- the retaining' means and said ring'.
